IMPROVEMENT 1N cULTrvAToRs.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it 'may concern: i

.Be it known that I, .loser-H H. BniNroN, of Thornbnry townslnp, Chester county, Pennsylvania., have invented a new and improved Oultivator; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to th'eI accompanymg sheets of drawings, and to the letters of reference marked thereon.

y The object of this invention is to simplify the management of cultivators, and increase their efficiency, which is elected by adaptingthe principle of Steerage for governing the plows working adjacent to or straddling a hoed crop, for the purpose of keeping them at regulated distances from the row, thereby correcting any irregularity in the movement of the horses The -person operating has the power of guiding the said plows with his feet, with the greatest nicety. While thoroughly cultivating the soil, and tearing up theweeds, he can prevent thee-slightest injury being..

done to the crop, lthe steerage being vindependent of the horses, and so simple that any one may control it` with the greatest ease.

vIt is also effected by the management of the plows of the same cultivator which work between the i'ows, for cultivating the soil, removing weeds, &c.

The attendant, by means of double levers, which connect with a transverse adjusting-bar, moving in in.- clined slots or openings at the sides of the implement, is enabled to regulate the depth the plows enter the soil, or p'ut a temporary pressure on them when they meet with vobstructions from the hardnessv of the ground.

The levers or arms, to which the plows are attached, are, in a measure, self-regulating, each swinging by an ordinary hinge, and having a spiral-spring pressure, or its equivalent, to press the plow of each into -the soil.

On reference to the accompanying sheets of drawings, making part of this .specication- Figure l is a plan view.

Figure 2 shows the method `of-hinging the levers or arms carrying the plows to the front of the implement.

Figure 3 is a side view of -the implement, showing the inclined slots, the transverse adjusting-bar, and the spiral spring on one oi' the plow-levers. The side-bar of the framing and the wheel on that side are, in part,`

sectioned, to show the arrangement of the aforesaid parts.

Figure 4 is a plan view of the steering-apparatus,

Its ends take into and move in the inclines D, fixed to the bottom at each side of the framing.

E E are lever-handles, on both sides of the drivers seat F, two being shown in this instance, though one can be made to answer the end sought.

. They have a vertical vibrating motion in the jaws d of the framing. v

They connect, by means of the rods e e, with the transverse bar C.

It will be readily seen that, as the handles are moved forward, the bar O is moved downthe inclines D, by which the plow-levers are gradually lowered, and a greater working depth given to the plows c. When the handles are moved in the opposite direction,'the

bar Gis moved up the inclines, which raises the p'lowj leversor arms a, lifting the plows c either clear of the soil, jor adj usting their working depth. IThe levers orv arms ci are, in a measure, selfregulating, Each vibrates on an independent hinge. being capcble of working on irregular land, and able to adjust itself to any irregularities, without disturbing the rest of the machine.

Each lever is provided with a spiral spring, G, which is retained in its relative position by means of a yoke, f, fixed vertically to the transverse bar C.

The levers g g, which carry the independent plows working adjacent to the rows 0f corn, are guided by the feet of the driver, on the Steerage-principle, to correct any irregularity in the movement of the horses,v

as follows: I

H is a lever, formed in an arc of a circle, and vibrates or rocks horizontally on a piu, h, in the front bar of the framing.

i is a projection of the said lever, to which are Xed the ends ofthe chains or cords k k, which pass 4over the pulleys I, turning on the pins l l of the framing. Y The other ends ofthe said chains are fixed to the levers g g, which, at this point, are placed side by side, forming an eye, m, shown in dotted'lines, 1, which takes over a pin, n, of the pole K of the machine.

. The levers are parallel for a short distance, and then diverge suflicientl y to enable the plows to work on both sides of the row. n

The ends of the arc are provided with. steps o, for the feet of the driver.

It will be seen, as the driver presses with his feet, alternately, on the steps o, a horizontal rocking motion will be given to the lever H on the pin h that couples it to the vfront bar of the framing, which motion is imparted to the plows on the levers or arms g g adjacent to the rows', by the mechanism hereinbefore shown,

and enables the. driver to cultivate close to the row mechanic to devise an incline of different construction,

and accomplish the endsought.

I do not confine myself to the mechanismherein a, together with e transverseliar, moving in inclines,

whereby to regulate the depth the plows enter the soil,

and to accommodate them to any unevennessof the ground. v

In testimony whereof,V I hereunto sign my nameto this specicetion, in presence of two subscribing Witmesses.v
